(GRANTED UNDER THE ACT OF MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370G. 757) The invention described herein may be manufactured and used byor for the Government for governmental purposes, without the payment tome of any royalty thereon.

This invention relates to a holder for pyrotechnic cartridges.

In discharging signal cartridges the usual practice consists in placingthe cartridge in the barrel of a pistol which contains a conventionalfiring mechanism. The pistol can only be employed, however, withcartridges of limited size and moderate propellant charge.

The principal object of the present invention is to provide a holder forsupporting a large cartridge carrying a heavy propellant charge.Inasmuch as the holder is primarily intended to be carried by aircraftand in proximity to the seat of an occupant a primary consideration inits design has been minimum size and weight. While fulfilling theserequirements the present holder is arranged to be adjusted for varyingangles of departure, and to permit the operations of mounting andremoving the cartridge to be conveniently performed with one hand.

With the foregoing and other objects in View, the invention resides inthe novel arrangement and combination of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed maybe made within the scope of what is claimed without departing from thespirit of the invention.

A practical embodiment of the invention is illustrated in theaccompanying drawings, wherein:

Fig. 1 is a view in side elevation of the im- 1 proved holder with acartridge carried there- Fig. 2 is a view in front elevation of theholder;

Fig. 3 is a plan view thereof;

Fig. 4 is a detail longitudinal sectional view shawing the plunger inposition for loading; an

Fig. 5 is a view similar to Fig. 4 and showing the plunger in retractedor unloaded position.

Referring to Figs. '2 and 3 the holder comprises a frame includingspaced side plates 6 having a flange 7 for receiving a bolt 8 passingthrough a support member 9 which in the case of aircraft would be therail surrounding the cockpit. The side plates are preferably connectedat their lower extremities by a bar 10 which accurately spaces them andinsures their'parallel relationship.

The side plates'fiare provided with aligned apertures 11 constitutingbearings for receiving the trunnions 12of a cradle 13 fitting betweenthe "side plates. For purposes of assembly the trunnions'areeachinserted in a socket 14 of the cradle and are conveniently securedthereto by a screw 15.

One of the trunnions is provided with an annular head lfi'positionedexternally of the side plate and having peripheral notches or recesses17 for receiving a lug 18 on a spring 19. The lower end of the spring issecured by a screw 20to a block or projection 21 on the side plate whilethe upper end of the spring extends through an aperture 22 in the flange7. The recesses 17 and the lug 18 are complementarily inclined to enablethe lug to be cammed out of engagement when pressure is applied torotate the cradle.

Referring to Figs. 4: and 5 the cradle 13 is essentially a tubularmember in which is mounted a bolt 23 of greater length than the cradle.The upper or head portion 24 of the bolt adapted to fit in the socket 25of the cartridge 26 has a sliding fit in the tube while the reduced stem27 is embraced by a spring ranged to engage in the annular groove 36 ofthe cartridge when the cartridge is placed on the bolt and rests againstthe annular head 37 of the cradle. i I

The bolt is normally retained in the re tracted or unloaded positionshown in Fig.

5, both to protect the portion 24 and to prevent interference with theoperator. Rotation of the bolt to position the pin 31 in the slot 32Will enable the spring to come into play and move the bolt forward tothe position shown in Fig. 4: Where it is rigidly held upon beingrotated to engage the pin 31 in the offset. The cartridge may noWbeplaced on the bolt Where it is securely held. by-the catch 34. Thecartridge serves as a barrel and carries a firing mechanism38,.p-being'i'n the present instance a friction igniter, for setting offthe propellant charge 39 to project the signal or pyrotechnic charge 40.The

emptycartridge case is ejected by merely 'rehead of the bolt, a pincarriedby the bolt,

and a guidewaywithoffset terminals in the cradle for recivi-ng the pinand limiting movement of the bolt.

2. In a cartridge holder, a frame including side plates, a cradletrnnnioned inthe side plates, means for holding the cradle in positionof angular adjustment, a bolt of greater length than the cradle andreciprocal therein, a spring latch in the head of the belt, a; springnormallytending to extrude the head of the bolt, a pin carried by thebolt, and a guide-Way in the cradle for receiving the pin and limitingmovement of the-bolt.

3. In a cartridge holder, a support, a cradle trunnioned in the support,means for holding the cradle in position of angular adjustment,

bolt mounted in the cradle for limited reciprocal movement, a springlatch in one end of the bolt, a spring normally tending-to extrude thelatch end of the bolt, and means for rigidly connecting the bolt to thecradle at the limits of its stroke.

4. In a. cartridge holder, a support, a cradle trunnioned in thesupport, a bolt mounted in the cradle for limited reciprocal movement, aspring latch in one end of the belt, a spring normally tending toextrude the latch end ofthe bolt and means for rigidly connecting thebolt tothe cradle at the limits of its.:stroke. 5..)In a cartridgeholder, a casing, a bolt in the casing movablelongitudinally to projectfrom one end of the casing, means on said projecting-endoi the belt forholdinga cartridge, and means for rigidly securing the boltto the casingat the limits'of its longitudinal movement. a r
